UNITED STATES PATENT GEETCE GEORGE D. DUDLEY, OF LOWELL, MASS., ASSIGNOR TO EDWD. P. WOODS, DANL. SHERWOOD, AND GYRUS H.'LATHAM, OF SAME PLAGE.

IMPROVEMENT IN WIRES.

Specification formifngupart of Letters Patent No. 145,285, dated December 9, 1873 application led January 6, 1873.

configuration in cross-section, in order that when such wire is finished and twisted the face of the wire that reilects the light will cause it to present a pleasing and tasteful appearance, which is due to the angle at which the light shall strike it.

The object of this invention is to produce a wire that will have the form adapted to such purpose; and it consists in the form of the wire, as will be more fully described hereinafter.

In the drawings, Figure l'is a longitudinal view of the wire; Fig. 2, anenlarged transverse section of same; Fig. 3, a view of the wire partially twisted; Fig. 4, a view of two wires twisted together, and Fig. 5 a view of the rollers that form the grooves in the wire.

A represents a wire that is grooved at or nearly at right angles to its face, longitudinally, by being drawn throughbetween rollers to make the grooves into each side, of however many sides the wire may be formed, as it may be of rectangular, triangular, or have any number of sides desired. The grooves may be formed when the wire is iirst drawn, or they may be made by a subsequent or secondary operation by passing the Wire, already in rectangular or round shape, between rollers adapted to form the grooves in the face ofthe wire. The forming the grooves in the wire tends to strengthen the wire by making it more fibrous and compacting the fiber, while it also tends to greatly stiii'en it. After the wire is thus formed it can be iinished by plating or galvanizing, in order to prevent oxidation, or to beautify the surface of the wire, and when so iinished it is twisted, as seen in Figs. 3 and 4, when it forms asurface having an improved and beautiful appearance.

The wire having the grooves thereon, as above described, and when finished, is used for making what is known in the market as twisted-wire goods.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The wire A, having the longitudinal grooves in its faces, as herein described, as a new article of manufacture.
